10 # Chitoliro chosasunthika chachitsulo
Kufotokozera Kwachidule:
Kapangidwe kake:
Akunja awiri a zitsulo chitoliro 20-426
Zitsulo chitoliro khoma makulidwe a 20-426
Mapangidwe a Chemical:
● 10 Seamless steel pipe chemical composition:
Mpweya C: 0.07~0.14″ silikoni Si: 0.17 ~ 0.37 Manganese Mn: 0.35 ~ 0.65 Sulfur S: ≤0.04 Phosphorus P: ≤0.35 chromium Cr: ≤0.15 Nickel0 ≤0.
Katundu wamakina:
Makina amakina a chitoliro chachitsulo chosasunthika cha nambala 10:Kulimba kwachitsulo σb (MPa) : ≥410(42) Kuchulukira kwamphamvu σs (MPa) : ≥245(25) elongation δ5 (%) : ≥25 shrinkage yachigawo (%) : ≥5 , kuuma: osatenthedwa,≤156HB, kukula kwachitsanzo: 25mm.
High quality carbon structural steel:
No. 10 seamless steel pipe ilibe zinthu zina za aloyi (kupatula zinthu zotsalira) kupatula carbon (C) element ndi silicon (Si) ya deoxidation (nthawi zambiri osapitirira 0.40%), manganese (Mn) (nthawi zambiri ayi kuposa 0.80%, mpaka 1.20%) aloyi zinthu.
Chitsulo choterocho chiyenera kukhala ndi mankhwala komanso makina.Zomwe zili mu sulfure (S) ndi phosphorous (P) nthawi zambiri zimayendetsedwa pansi pa 0.035%.Ngati ikuyendetsedwa pansi pa 0.030%, imatchedwa chitsulo chamtengo wapatali, ndipo "A" iyenera kuwonjezeredwa pambuyo pa kalasi, monga 20A;Ngati P ikuyang'aniridwa pansi pa 0.025% ndipo S imayendetsedwa pansi pa 0.020%, imatchedwa chitsulo chowonjezera chapamwamba, ndipo "E" iyenera kuwonjezeredwa pambuyo pa kalasi kuti iwonetse kusiyana.Kwa zinthu zina zotsalira za alloying zomwe zimabweretsedwa muzitsulo ndi zida zopangira, monga chromium (Cr), faifi tambala (Ni), mkuwa (Cu), etc., zomwe zili Cr≤0.25%, Ni≤0.30%, Cu≤0.25%.Mitundu ina ya manganese (Mn) imakhala ndi 1.40%, yotchedwa chitsulo cha manganese.
No. 10 opanda zitsulo chitoliro chitoliro kuwerengera chilinganizo :[(m'mimba mwake m'mimba mwake - khoma makulidwe)* khoma makulidwe]*0.02466=kg/m (kulemera pa mita)
